Within your budget,you should be able to do very well. I also like detail,but not over the top bright. Something in the KEF line might work. One of the speakers rotate in my system is a pair of Nola Boxer 2’s. To me,they are anything but fatiguing. Other possibilities might be PSB, some British mini monitors. With the latter,you will probably want that bass reinforcement as they don’t dig that deep.
The best advice I think anyone can give right now is get out there and listen to as many different speakers as you can. This will help determine what will make your ears happy!
